My Experience with AR 15 Barrel Shims

I have been an avid shooter for many years and have owned multiple AR 15 rifles. One issue that I have encountered with these rifles is the alignment of the barrel and gas block. This alignment is crucial for proper functioning of the rifle and accuracy of shots.

In my early days of shooting, I did not pay much attention to the barrel alignment and often ended up with a less than satisfactory shooting experience. It was only when I started exploring different upgrades for my rifle that I came across AR 15 barrel shims.

At first, I was skeptical about their effectiveness and necessity. However, after doing some research and consulting with experienced shooters, I decided to give them a try. And let me tell you, it made a significant difference in the performance of my rifle.

One major benefit of using AR 15 barrel shims is that they help in aligning the gas block perfectly with the barrel. This ensures consistent gas flow to the bolt carrier group, resulting in smooth cycling and reduced recoil. Additionally, it also improves the accuracy of shots by reducing any potential misalignment between the barrel and gas block.

Another reason why AR 15 barrel shims are necessary is that they allow for easy installation

My Buying Guide on ‘Ar 15 Barrel Shims’

Introduction: Hi there! My name is [Your Name] and I have been an avid shooter for years. Recently, I decided to upgrade my AR 15 rifle with a new barrel and came across the need for barrel shims. After researching and testing out different options, I have put together this buying guide to help you choose the best AR 15 barrel shims for your rifle.

What are AR 15 Barrel Shims?

In simple terms, AR 15 barrel shims are thin metal or polymer pieces that are used to adjust the alignment of the barrel in relation to the receiver. They are typically used when installing a new barrel or when trying to correct any misalignment issues that may affect accuracy.

Why do you need AR 15 Barrel Shims?

The main purpose of using barrel shims is to achieve proper alignment between the barrel and receiver. This is crucial for accuracy as even a slight misalignment can cause shots to go off target. Additionally, if you are installing a new barrel, shimming can also help with headspace adjustment.

Types of AR 15 Barrel Shims:

  • Metal Shims: These are made from stainless steel or aluminum and are more durable compared to polymer shims. They come in different thicknesses and can be stacked on top of each other for precise adjustments.
  • Polymer Shims: These are made from high-strength polymer materials and are lightweight. They also come in different thicknesses but may not be as durable as metal shims.

Factors to Consider:

When looking for the right AR 15 barrel shims, here are some important factors to keep in mind:

  • Material: As mentioned earlier, metal shims are more durable but may add weight to your rifle while polymer shims are lightweight but may not last as long.
  • Thickness: The thickness of the shim will determine how much it will affect the alignment between your barrel and receiver. Thicker shims provide more adjustment options but may also require more filing or sanding down depending on your specific rifle.
  • Sizing: It is important to choose shims that fit your specific rifle model. Some manufacturers offer universal shims that can be trimmed down to fit any AR 15, while others have specific sizes for each model.

Tips for Using AR 15 Barrel Shims:

  • Cleanliness is key: Before installing the shim, make sure both the barrel and receiver surfaces are clean from any debris or residue. This will ensure a tight fit between the two components.
  • Precision is important: When stacking multiple shims, make sure they are aligned properly and evenly distributed around the circumference of the barrel. Any unevenness can affect accuracy.
  • Trial and error: If you’re not satisfied with your first shim configuration, don’t be afraid to try out different combinations until you find one that works best for your rifle.
